Waterproof. Reflective. Corrosion-proof. Insulating. One self-adhesive membrane that does the work of four — engineered for metal, concrete and solar-ready roofs.
ACC (Anti-Corrosion Coating) is a multi-layer, self-adhesive weathering membrane that bonds a reflective pure-aluminium and reinforced facing to a high-performance butyl rubber adhesive base. Peel the release film, press it down — no torching, no liquids, no specialist plant.
In a single application it waterproofs the roof, reflects the sun's heat, resists corrosion in harsh environments, and adds a layer of thermal insulation. It's built for retrofit and restoration as much as new build — ideal for ageing metal roofs, concrete decks, gutters, pipework and solar-ready rooftops.

Figures reflect the latest product generation, validated as performance benchmarks have been met.
A continuous butyl-backed seal with proven impermeability — sheds water across roofs, gutters, joints and penetrations.
Withstands acidic and alkaline exposure (pH 2–13) and salt spray — with a service life of 15+ years even in highly corrosive marine environments.
Holds reflectance and integrity through 10,000 hours of accelerated weathering — no powdering, cracking or delamination.
As a ground or roof reflector beneath bifacial PV, ACC lifted measured generation by 9.1% in field testing — turning a roof into a solar asset.
Self-adhesive application — no heat, no flame, no liquid membranes. Faster, safer installs with less specialist labour.
A service life of more than 25 years, backed by a 10-year product warranty.
